Profile: At one point, it was thought that Lo was set to close games for the Astros, or at least be a big part of a committee. But he ended up saving just two games in two months. What likely caused the team to shy away from using Lo in the role was his lack of control. He walked 13 batters in 19.1 innings, or 15.5% of the batters he faced. An inability to throw strikes wasn't something new to Lo, as he has struggled with his control at times throughout his minor league career. Without the promise of a high strikeout rate to offset the control issues, he's unlikely to sniff the ninth inning in a close game anytime soon. (Mike Podhorzer)

The Quick Opinion: With an unsettled bullpen, the opportunity was there for Lo to take over closing duties for the Astros and run with the job. Alas, his control deserted him and he simply doesn't possess the skill set to be trusted in a high-leverage situation.
